Echinacea plant named ‘Balsomcor’

ABSTRACT

A new and distinct cultivar of  Echinacea  plant named ‘Balsomcor’, characterized by its single-type, red-orange colored inflorescences, medium green-colored foliage, and moderately vigorous, compact-upright growth habit, is disclosed.

Latin name of genus and species of plant claimed: Echinacea×hybrida.

Variety denomination: ‘Balsomcor’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant botanically known as Echinacea×hybrida and hereinafter referred to by the cultivar name ‘Balsomcor’.

The new cultivar originated in a controlled breeding program in Elburn, Ill. during September 2007. The objective of the breeding program was the development of Echinacea cultivars with a single inflorescence form having imbricate ray florets and a well-branched, compact growth habit.

The new Echinacea×hybrida cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Echinacea×hybrida breeding selection designated ‘E30-2’, U.S. Pat. No. 7,982,110, characterized by its single-type, red-orange colored flowers, medium green-colored foliage, and moderately vigorous, upright growth habit. The male (pollen) parent of the new cultivar is from a bulk pollen mix of seven proprietary Echinacea×hybrida breeding selections designated ‘E30-1’ through ‘E30-7’, U.S. Pat. No. 7,982,110, characterized by their single-type, shades of red-orange colored inflorescences, medium green-colored foliage, and moderately vigorous, upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during October 2008 in a controlled environment in Elburn, Ill.

Asexual reproduction of the new cultivar by in vitro propagation since October 2008 in West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balsomcor’ as a new and distinct cultivar of Echinacea plant:

-   -   1. Single-type, red-orange colored inflorescences;     -   2. Medium green-colored foliage; and     -   3. Moderately vigorous, compact-upright growth habit.

Plants of the new cultivar differ from plants of the female and male parents primarily in inflorescence color and growth habit. The new variety is more compact and has a different red-orange inflorescence color shade than the parent plants.

Of the many commercially available Echinacea cultivars, the most similar in comparison to the new cultivar is Echinacea Big Sky™ Summer Sky, ‘Katie Saul’, U.S. Plant Pat. No. 18,783. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Katie Saul’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have an inflorescence color,         specifically ray floret color, different from plants of ‘Katie         Saul’;     -   2. Plants of the new cultivar have wider ray florets than plants         of ‘Katie Saul’; and     -   3. Plants of the new cultivar are more compact, as measured by         plant height, than plants of ‘Katie Saul’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balsomcor’. Three plants per 1 gallon container were grown for 16 weeks in a greenhouse in Elburn, Ill.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balsomcor’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2011 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from in vitro plantlets and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in Elburn, Ill. in 1-gallon pots for 16 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 45° F. to 65° F. (7.2° C. to 18.3° C.) during the day and approximately 35° F. to 45° F. (1.7° C. to 7.2° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
